## Ncert Class 6 Mathematics Solutions Chapter 2 Whole Numbers

Welcome to NCTB Solutions. Here with this post we are going to help 6th class students for the Solutions of NCERT Class 6 Mathematics Book, Chapter 2, Whole Numbers. Here students can easily find step by step solutions of all the problems for Whole Numbers, Exercise 2.1 Also here our mathematics teacher’s are solved all the problems with easily understandable methods with proper guidance so that all the students can understand easily. Here in this post students will get chapter 2 solutions. Here all the solutions are based on NCERT latest syllabus.

Whole Numbers Exercise 2.1 Solution :

(1) Write the next three natural numbers after 10999.

Solution :

The next there natural number after 10999 are 11000, 11001, 11002

= 10999 + 1 = 11000,

= 11000 + 1 = 11001

= 11001 + 1 = 11002

(2) Write the three whole numbers occurring just before 10001

Solution

The three whole numbers occurring just before 10001 are 10000, 9999 and 9998

10001 – 1 = 10000,

10000 – 1 = 9999,

9999 – 1 = 9998

(3) Which is the smallest whole number?

Solution :

= Zero (0) is the smallest whole number.

(4) How many whole numbers are there between 32 and 53?

Solution :

There are 20 whole numbers between 32 and 53 Such that 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 50, 51, 52

How to find Whole Numbers between two numbers :

= 53 – 32

= 21 + 1

= 22

Subtract two number and the resultant is added by 1.

(5) Write the successor of :

(a) 2440701

(b) 100199

(c) 1099999

(d) 2345670

Solution :

(a) The successor of 2440701 is 2440702

= 2440701 + 1

= 2440702

(b) The successor of 100199 is 100200

= 100199 + 1

= 100200

(c) The successor of 1099999 is 1100000

= 1099999 + 1

= 1100000

(d) The successor of 2345670 is 2345671

= 2345670 + 1

= 2345671

(6) Write the predecessor of :

(a) 94

(b) 10000

(c) 208090

(d) 7654321

Solution :

(a) The predecessor of 94 is 93

= 94 – 1

= 93

(b) The Predecessor of 10000 is 9999.

= (10000 – 1)

= 9999

(c) The predecessor of 208090 is 208089

= 208090 – 1

= 208089

(d) The predecessor of 7654321 is 7654320

= 7654321 – 1

= 7654320

(7) In each of the following pairs of numbers, state which whole number is on the left of the other number on the number line. Also write them with the appropriate sign (>, <) between them.

(a) 530, 503

(b) 370, 307

(c) 98765, 56789

(d) 9830415, 10023001

Solution :

(a) 530, 503

503 is the left of 530.

503 < 530

(b) 370, 307

307 is the left of 370.

307 < 370

(c) 98765, 56789

56789 is the left of 98765.

56789 < 98765

(d) 9830415, 10023001

9830415 is the left of 10023001.

9830415 < 10023001

(8) Which of the following statements are true (T) and which are false (F) ?

(a) Zero is the smallest natural number.

(b) 400 is the predecessor of 399.

(c) Zero is the smallest whole number.

(d) 600 is the successor of 599.

(e) All natural numbers are whole numbers.

(f) All whole numbers are natural numbers.

(g) The predecessor of a two digit number is never a single digit number.

(h) 1 is the smallest whole number.

(i) The natural number 1 has no predecessor.

(j) The whole number 1 has no predecessor.

(k) The whole number 13 lies between 11 and 12.

(l) The whole number 0 has no predecessor.

(m) The successor of a two digit number is always a two digit number.

Solution :

(a) This statement is False.

As because One is the smallest natural number.

(b) This statement is False

As because 398 is the predecessor of 399.

(c) This statement is True.

(d) This statement is True.

(e) This statement is True.

(f) This statement is False.

Correct statement is, all natural numbers are whole numbers.

(g) This statement is False.

Because, The predecessor of a two digit number is a single digit number or two digit number.

(h) This statement is False.

Because, 0 is the smallest whole number.

(i) This statement is True.

(j) This statement is False.

Because, the whole number 1 has 0 predecessor.

(k) This statement is False.

Because, the whole number 13 lies between 12 and 13.

(l) This statement is True.

(m) This statement is False.

Since, the successor of 99 is 100 i.e. three digit number.
